The multicenter study was part of the Long Lasting Memories (LLM) project (www.longlastingmemories.eu), which was funded by the European Commission (Information and Communication Technologies Policy Support Program (ICT-PSP) for a three year period (2009-2012). It used a pre-post-test design with the between-participant factor group [intervention vs. passive control]. Post-test was conducted within 2 weeks after completion of the exercise period. Interventions were carried out in Athens and Thessaloniki (Greece) within day care centers, hospitals, senior care centers, a memory outpatient center, local parishes, at university campus facilities (university community installations), and at participants' homes.
